Given that a^b = x, evaluate the following: a^b+2--->(the 2 is added to the b in the exponent so the 2 is also an added exponent next to the b)

x* a^2

Step-by-step explanation:

a^b = x

Remember that when we add exponents, we multiply the bases

x^2 * x*4 = x^(2+4)

We want a^ (b+2) so that means a^b * a^2

We need to multiply both side by a^2

a^b * a^2 = x * a^2

a^ (b+2) = x* a^2

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
