Algebra help is needed please

which expression is equal to (3^(3/4)y^(-1/4))^4.Here, y>0 a) 27y b) 9/y c)27/y d) 81y^4 e) y/27 will vote for best answer!!-c)27/y-c. (3^(3/4)*y^(-1/4))^4 = 3^(12/4)*y(- 1) = 27/y, (e)-Right result

Quick algebra question!!

simplify this expression using only positive exponents. (here, x>0 and y>0) ((9y^-2)/(x^2))^(-1/2) the 9y^-2 is above the x^2 and the -1/2 is the exponent outside of the parenthesis of the expression.

Help me solve this equation

4/3-4x=10/3 Show your work.-If you mean four-thirds minus four-x equals ten-thirds, then this is how you do it. 4/3-4x=10/3 -4x=10/3-4/3 -4x=6/3 -4x=2 x=2/-4 x=-1/2--6/3=4x -2=4x x=-1/2 Answer!!!-4/

Algebra help!! please!!

which expression is the same as log[5][5(x-4)] a) log[8]5x-log[8]20 b) 5 log[8](x-4) c) log[8]x d) log[8] 5+log[8](x-4) will vote for best answer!!-log mn = log m + logn So we have log5+ log(x-4) -Im

Use substitution to compute the following indefinite integrals.

(a)∫ln^3 x / x dx (b)∫sin^5 xcos xdx (c)∫e^tan x / cos^2xdx (d)∫e^x  sin(e^x)dx Please show your work, thanks!-a) u = ln(x) du = dx / x int(u^3 * du) => (1/4) * u^4 + C => (1/4) * ln(x)^4 + C

Converting to logarithmic form

convert these from exponential form to logarithmic form please 3^5=243 5^3=125 thanks!!-log3^243=5 log5^125=3-y = log (base b)x is equivalent to x = b^y So...its easy for you to now just switch form
