Question

In the given figure find the value of xX+20°x+3° x+7°

Answer 1

x X +20^0x + 3^0 x + 7^0 where the symbol ^ represents to the power of.

= x ( x + 20^0 x +3^0 x +7^0)

= x (x+x+1+1)... Using the law of Indices.(Exponents) where anything to the power 0 becomes 1 (a^0 =1)

= x (2x+2)

=2x^2+2x

Using the law of Factorisation:
Taking 2x as a common factor:

=2x(x+1) as your answer.

Hope you got it right.

Happy learning.
