Question

Solve the equations involving exponents

1. Solve 5^4x5^8=?

2. 11^18/11^-4=?

Answer 1

When you multiple same numbers with different exponents, the exponents add. Example x^2 * x^3 = x^4
When you divide same number with different exponents, the number subtracts

1. 5^4 * 5^8 = 5^12
2. 11^18/ 11^-4 = 11^22
