Question

Which step do I do first?
T=(3.14)√(2.9/32)

Answer 1

first 2.9/32, than square root, then multiplication

Answer 2

so 2.9/32=.9 and then the √ of .9 is .3?

Answer 3

no. square root of 0.09 is 0.3 . Square root of 0.9 is between 0.9 and 1

Answer 4

I'm confused, I used a calculator

Answer 5

You should. These are not easy to calculate without a calculator

Answer 6

Okay but you just told me I was wrong so now I'm confused

Answer 7

If you use a (scientific enough) calculator, it will calculate the expression in order

Answer 8

I was using my phone. I have a graphing calculator should I go get that and use it?

Answer 9

First 2.9/32 = 0.091 ---> (3.14)*sqrt(0.091)
Then sqrt(0.091) = 0.3 ---> (3.14)*0.3
Then 3.14*0.3 = 0.942

Answer 10

Engineering students use one of those:

But you can find nice calculators for iPhone and Androids

Answer 11

3.14*.3 is .945

Answer 12

I'm using a graphing calculator now.

Answer 13

No. It is 0.942 . Probably your calculator is calculating it wrong. But it is not very important. Because we already omitted some digits after division and square root operations.

Answer 14

A graphic calculator is useless for that kind of questions

Answer 16

\[T=3.14 \sqrt{\frac{ 2.9 }{ 32 }},T=3.14\sqrt{\frac{ 5.8 }{ 64 }}=\frac{ 3.14 }{ 8 }\sqrt{5.8}\]

Answer 17

\[T=3.14 \sqrt{\frac{ 2.9 }{ 32 }},T=3.14\sqrt{\frac{ 5.8 }{ 64 }}=\frac{ 3.14 }{ 8 }\sqrt{5.8}\]
