| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Simplify the expression: |
|
2 |
Step |
Multipling the exponents of same variables |
\$ (48x^5y^3)(3x^(-9)y^2) \$ |
3 |
Step |
Separate all the variables and numbers |
\$ (48 × 3 ) (x^5y^3 × x^(-9)y^2 )\$ |
4 |
Formula: |
By using the formula |
\$a^m \times a^n = a^(m+n)\$ |
5 |
Step |
After simplification |
\$ 144 x^(5+(-9))y^(3+2)\$ |
6 |
Step |
After simplification |
\$ 144 x^(-4)y^5\$ |
7 |
Formula: |
After simplification |
\$ a^-n = 1/a^n\$ |
8 |
