Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Simplify the expression: |
|
2 |
Step |
Multipling the exponents of same variables |
\$ (9x^(-6)y^2)((-7)x^(-2)y^(-3)) \$ |
3 |
Step |
Separate all the variables and numbers |
\$ (9 × -7 ) (x^(-6)y^2 × x^(-2)y^(-3) )\$ |
4 |
Formula: |
By using the formula |
\$a^m \times a^n = a^(m+n)\$ |
5 |
Step |
After simplification we get |
\$ -63 x^(-6+(-2))y^(2+(-3))\$ |
6 |
Step |
After simplification we get |
\$ -63 x^(-6-2)y^(2-3)\$ |
7 |
Step |
After simplification we get |
\$ -63 x^(-8)y^(-1)\$ |
8 |
Formula: |
By using the formula |
\$ a^-n = 1/a^n\$ |
9 |
Step |
After simplification we get |
\$ -63/(x^8y)\$ |
