No. The square root of 84 is an irrational number

First note that 84=4x21 and 4 is a perfect square. So square root of (84)=square root (4x21)=Square root (4) Square root (21)= 2 multiplied by the square root of 21. You can also write this using rational exponents, but this is not in radical form. It is an equivalent expression, however. 2 x (21)1/2

If you mean 84 squared then it is 84*84 = 7056 If you mean the square root of 84 then it is 2 times the square root of 21 which is an irrational number

The square root of 7056 is 84.

Root 64 is 8, if by root you mean the square root. Then the problem become -square root 84(6+8) which is the - square root of 84(14) But square root of 84 is 2(square root of 21) so the final answer comes from -2(square root 21)x14 which is -28square root (21)

No because it is 2 times the square root of 21 which is an irrational numberThe square root of 84 is not a rational number

Expressed as a surd, the square root of 84 is equal to 2 sqrt (21). √84 = √(4 x 21) = √4√21 = 2√21

It is: 2 times the square root of 21 and it's an irrational number

irrational

√84 = √(4x21) = √4 √21 = 2 √21

The square root of 84 is irrational and is approx 9.1652.

if you have a TI-84 you can hit math, then go down to the x before the square root sign

6x^2=84, x^2=14, root(14) = x x = Plus or minus square root of 14, or 3.741...

√6 x √14 is the same as √(6x14). This equals √84, which can be simplified to 2√21.

81 - 3 = 78 81 - -3 = 84
