Need help with expressing this.

Please use step by step.

Thank you.

Step-by-step explanation:

Move a^-4 to the denominator using the negative exponent rule b^-n = 1/b^n.

Move b^-2 to the numerator using the negative exponent rule 1/b^-n = b^n.

Hence, if we express this equation with positive exponents, we'll get the answer 2b^2/5a^4.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
