Put x = 1
the first exponent is
since x = 1
our new expression becomes
9^1
in mathematics, anything number rasied to the power of one is equal to that same number
Therefore, 9^1 = 9 x 1
= 9
Therefore, the expression is not equal to the exponent
for the second exponent
3^x
since x = 1
therefore, 3 raised to the power of one is 3
3^1 = 3 x 1
= 3
The second exponent which is 3^x is equal to 3 and not 9
for the third exponent
x^3
since x = 1
so we have, 1^3
one raised to any power is 1
1^3 = 1 x 1 x 1
1^3 = 1
Therefore, x^3 = 1
