I think the answer is 1000000000 since you're doing powers.
Answer:
b and c
Step-by-step explanation:
25% is 1/4 and 25/100 is 1/4. so is 0.25. therefore, the answers are 25/100 and 0.25.
The answer of 3542=48, if the given is 1243=21 , 2415=36, 3241=25, 4521=27.
Step-by-step explanation:
The given is,
1243=21
2415=36,
3241=25,
4521=27
Step:1
For, 1243 = 21
Above is solved by,
(1+2)×(4+3)=21
(3)×(7)=21
21=21
For, 2415 = 36
Above is solved by,
(2+4)×(1+5)=21
(6)×(6)=36
36=36
For,3241= 25
Above is solved by,
(3+2)×(4+1)=25
(5)×(5)=25
25=25
For, 4521= 27
Above is solved by,
(4+5)×(2+1)=27
(9)×(3)=27
27=27
For, 3542 = ?
Above is solved by,
= (3+5)×(4+2)
=(8)×(6)
3542=48
Result:
The answer of 3542=48, if the given is 1243=21 , 2415=36, 3241=25, 4521=27.
The way to figure this one out is move the 81 over to the other side so you have the equation 16x^4 = 81. Since 81 is not divisible by 16 you have to think of another way to simplify. 16 is a perfect square, x^4 is a perfect square, and 81 is a perfect square. So take the square root of both sides to begin the simplification. 4x^2 = 9. Divide both sides by 4 to get x^2 = 9/4. 9 and 4 are both perfect squares, so undo the square on the x by taking the square root of both sides: x = +/- 3/2.
