3 to the seventh power times 3 to the fourth power?

If we are in polynomial...

3^7 x 3^4 = 9^11

we should multiply first the "Base" and then add the "Exponent"

Base - 3,3
Exponent - 9,11

3^7 * 3^4 = 3^11 = 177,147

3^7 = 2187
3^4 = 81

2187 * 81 = 177,147.

3^7 x 3^4 = 3^11

3^7 x 3^4
= 3^(7 + 4)
= 3^11
= 177147

3 to the 11th power. You add the exponents. (seven 3`s times four 3`s makes eleven 3`s)

3^7 * 3^4 = 3^11

3^11= 9^5 * 3= 6561 * 27

3^7 = 3x3x3x3x3x3x3= 2187
3^4 = 3x3x3x3= 81

2187x81=177147 = 3^11
