Answer:
The number is 3.
Explanation:
Let "The square of the number" be x^2.
Let "the cube of the same number" be x^3.
"product" means multiplication.
x^2 • x^3 = 243
Multiply. To multiply, add the exponents.
x^5 = 243
Take the 5th root of both sides. You can do this on many scientific calculators with a x^y button. Or raise 243^ (1/5)
1/5 power is the same as 5th root.
You might do it in your head by thinking "what number to the 5th power is 243"
x = 3
Check 3^5 = 243
also
3^2 • 3^3 = 43
9 • 27 = 243
243 = 243 check
