Step-by-step explanation:

If I have interpreted the question correctly it is:

3*3*3*3 *x*x*x*x = 34

81 x^4 = 34

x^4 = 34/81

x = +/- (⁴√34) / 3 is the exact answer , or:

x = +/- 0.805 to nearest thousandth.

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
