Anyone know which one is the right one
sergiy2304 [10]

1) the square root of 64=8

2) The square root of a^4=a^2

3) b^5=b√b

so the first amount simplifies to 8a²b²√b

4) ∛64=4, as 4×4×4=64

5) ∛a^5=a√a²

6)∛b^4=b√b

so...the second amount is equal to 4ab∛a²b

The last one should be correct

Hope this helped :)

Jamelia estimates the square root of 72 in the following way:
Zigmanuir [339]
Part a)
we have that
<span>√72
</span>√72-----> √(2*36)=√2*√36 is not 2*√36------> this is the error
√2*√36=√2*√6²-----> √2*(6)----> 6√2
<span>
</span><span>alternative method</span><span>
72 is equal to-------> 2</span>³*3²
therefore
√72-----> √[2³*3²]----->√ 2³*√3²-------> (2√2)*(3)-----> 6√2

Part b)<span>Estimate the square root of 72 to the nearest tenth
</span>
we know that
√2 is equal to 1.41
so
√72=6√2------> 6*1.41-----> 8.46----> 8.5

the answer Part b) is 8.5
