let me help you out here, by explaining what YOU need to do to arrive at your accurate answer.

OK?

Seperate your problem into two parts:

1) 15 divided by 5….write down the answer.

2) 10 times 3 (squared)…write down the answer

3) take the first answer (3? 4? 5?)and

divide it by the second answer (30? 60? 90?)…

4) Bear in mind that ANY number, SQUARED, is the number TIMES ITSELF!

You can do it, kiddo!

PS…I hate math, too — but you GOTTA learn this stuff.

=[15/(-5)] x 9

=[-3] x 9

= -27

b) [(15/5)-10] x 3(to the power of 2)

=[3-10] x 9

= [-7] x 9

= -63

c) [15/5]-[10 x { 3 (to the power of 2)}]

=[15/5]-[10 x 9]

=3-90

=-87

There u go!!

– 5(10 X 3x^2) = 5b – 15 => – (10 X 3x^a) = b – 3 =>

x^2 = -(b – 3)/10X3 => x=squarerootof(-(b – 3)/10X3)

now you plug an appropiate “b” in there

You really need to be able to do these very simple things for yourself, they’re very very basic. If you’re not able to do even that you will have VERY low SAT scores and never get into college

next time ask this question in the math section

b)(15÷5)-10 x (3 exponent 2)=-63

c)(15÷5)- (10 x (3 exponent 2))= -87

a) [15/(5 – 10)] * (3^2)

b) [(15/5) – 10] * (3^2)

c) (15/5) – (10*(3^2))

If we write them without the unnecessary parentheses, it would be

a) [15/(5-10)] * 3^2

b) (15/5 – 10) * 3^2

c) 15/5 – 10*3^2

Note that the last one is what you get if you just follow the standard order of operations.

– 5(10 X 3x^2) = 5b – 15 => – (10 X 3x^a) = b – 3 =>

x^2 = -(b – 3)/10X3 => x=squarerootof(-(b – 3)/10X3)

now you plug an appropiate “b” in there
