Answer:
3-(1/3)^4 = 242/81
Step-by-step explanation
to raise a fraction to a power, raise the numerator and denominator to that power. Making it 3-1/81
then calculate the difference, making your answer 242/81 (or 2 wholes and 80/81)
Ii.First ,expand: 5(x-2)=32
5x-10=32
bring 10 to the other side (add it to 32)
5x=42
divide both sides by 5 to get x
x=42/5
x=8.4
iii.Expand 5+2(x+3)=21
5+2x+6=21
bring 5 and 6 to the other side
2x=21-5-6
2x=10 divide both sides by 2
x=5
You add 25 and 12 i think
Answer:
Step-by-step explanation:
i) the length of each side of the block is 154m.
