Question

How can I solve an unknown exponent, e.g 2^y?

Donagan

Top Answerer

The expression would have to be part of an equation before you could find the value of y.

Question

How do I do an algebraic equation with 2 variables, that also has squares?

Community Answer

You add up the like terms, different variables do not add up. Also, if you are adding, the exponents have to be the same on the top right corner of the coefficients.

Question

What is the law of exponent say?

I_l1ke_gam3s

Community Answer

First law of exponents: (a^b)(a^c) = a^(b + c). Second: x^x/x^y = x^(x - y). Third: (x)^y^z = x^(yz).

Question

What is the square root of negative 27 - (-3)?

Community Answer

Let's assume you mean (√-27) - (-3). The square root of a negative number is an imaginary number incorporating "i" (or the square root of (-1). The square root of -27 can be expressed as 3i√3. So (√-27) - (-3) = (3i√3) + 3, which would more typically written 3 + 3i√3.

Question

What is 7h to power 2 + 8h to power 2?

Community Answer

Let's assume you mean 7h² and 8h². They are "like terms" and can be combined to become 15h². If you mean (7h)² and (8h)², that's a different question. (7h)² + (8h)² = (49h²) + (64h²) = 113h².

Question

How do you solve 2.35 x 10^3 = x over (.0842)(.0842)?

Community Answer

Let's assume the equation is this: (2.35) (10³) = x / (.0842)². Multiply both sides of the equation by (.0842)²: (2350)(.0842)² = x. So x = (2350)(.0842)(.0842) = 16.66.
