How do I simplify (2x1/4) -4th power?
alina1380 [7]
Since the 2 and x^1/4 are multiplying we can do the math separately and then just multiply them afterwards

2^-4 is the same as 1/(2^4) which is 1/16

(x^1/4)^-4    (POWER RULES REVIEW)
                          2 exponents of same base you just add (basically multiply                                                                                                              the two)
so x^(1/4x-4)  = x^(-1)

which is just 1/x

so the answer is 1/16x

Is the ratio 4.2:1.5 proportional to the ratio 12.6:4.5? Explain.<br> PLEASE HELP I SUCK AT MATH!!!!
Lana71 [14]

Yes, the two ratios are proportional to each other. The multiplier from the first ratio to the second ratio is 3. For example, 4.2 x 3 = 12.6 and 1.5 x 3 = 4.5. Basically, to figure out if two ratios are proportional to each other, just divide the smaller number into the bigger number for both corresponding numbers. If they're the same ---> Proportional. If they're not the same ---> Not Proportional
