Question

simplify 3 by 4 whole power minus 2 divided by 4 by 5 whole power minus 3 whole multiplied by 3 by 5 whole power minus2
​

Answer 1

Answer:

Ans=2.528

Step-by-step explanation:

so the question is (3/4)*-2/(4/5)*-3*(3/5)*-2:

firstly convert the negative powers into positive:(4/3)*2/(5/4)*3*(5/3)*2

so it will be as:(16/9)/(64/125)*(25/9)

for making it easy make reciprocal of the second and change division into multiplication :(16/9*64/125)----16*64=1024 and 9*125=1125

divide both number now---->0.190

now multiply that with:0.190*25/9

=2.528

Answer 2

Answer:

1024/405

Step-by-step explanation:

• (3/4)^-2 / (4/5)^-3 * (3/5)^-2

Since each term has a negative power, reciprocate each fraction.

• (4/3)^2 / (5/4)^3 * (5/3)^2

Now, we need to change the division symbol to a multiplication symbol.

So reciprocate the second term again.

• (4/3)^2 * (4/5)^3 * (5/3)^2

After this, square/cube the fractions to remove the exponents.

• (16/9) * (64/125) * (25/9)

After multiplying, we get:

• 1024/405

This fraction cannot be further simplified.
