if z 2 square equal 49 what are the solutions

Sagot :

Answer ↓

z = 7, z = -7

Calculations ↓

z² = 49

Take the square root of both sides to find what z equals

z = 7

Is that the only solution? Is 7 the only number that can be multiplied by itself and have a result of 49? No, there's another number. This number is -7.

So the solutions are ↓

7, -7
