 Hi and welcome to the session. I am Asha and I am going to help you solve this question of your textbook which says write the degree of each of the following polynomials. As we know the highest power or the exponent of the variable in a polynomial is called the degree of the polynomial. Therefore, let us write it down degree of a polynomial the highest exponent of or the highest power of the variable. This is the key idea of which you should be aware before finding the solution of this problem. Let us now start with the first one. First is 5x cube plus 4x square plus 7x. Now here on observing this algebraic expression we find here that the variable in this polynomial is x, exponents are 1, 2 and 3 and the highest exponent is 3. Therefore, the degree of this polynomial is equal to 3. So this completes the first part and now proceeding on to the next one where we have to find the degree of 4 minus y square. Now here the variable is y and the highest exponent of y is what is the exponent of y. Here there is only one term which contains y and the highest exponent is 2. Therefore, degree of this polynomial is 2. So this completes the second part and now proceeding on to the next part which is 5t minus root over 7. So this is a polynomial with variable t. Highest exponent of t is 1. Therefore, degree of this polynomial is equal to 1. This completes the third part and now proceeding on to the last one which is 3. Now 3 can be written as 3 into x raise to the power 0 since x raise to the power 0 is equal to 1 and 3 multiplied to 1 gives 3. Therefore, writing 3 as 3 into 1 and in place of 1 writing x raise to the power 0. Now on observing this monomial we find that here the variable is x and its degree is 0 since exponent of x is 0 and this polynomial exponent of x is 0 and hence the degree of this polynomial is 0. So this completes the fourth part and hence the solution. So hope you enjoyed this session. Take care and have a good day.
