Question

If x = 3 and y = 2, calculate 2x^2y^3

Answer 1

144

Explanation:

First, put the values of your variables into the equation.

`2(3)^(2)(2)^(3)`

We can split this equation to solve them one at a time.

`2(3)^(2)`

First, multiply the exponent because of PEMDAS rules.

`2(9)`

Then, multiply the coefficient.

`18`

Next, solve the next part of the equation.

`(2)^(3)`

Multiply by the exponent.

`8`

Finally, recombine the two equations together.

`18 * 8 = 144`

Answer 2

144

Explanation:

2x²y³ ← substitute x = 3 and y = 2 into the expression

= 2 × 3² × 2³

= 2 × 9 × 8

= 18 × 8

= 144
