First you need to distribute the exponent into the terms for the first parenthesis.
(-3x²y³)³ = (-3)³ * (x²)³ * (y³)³
= -27 *x⁶ *y⁹
= -27x⁶y⁹
Then you multiply -27x⁶y⁹ by x²y.
You just need to add the exponents of x and y:
-27x⁶⁺²y⁹⁺¹
= -27x⁸y¹⁰
Given:
The value is
.
To find:
The values from the given options which are equal to the given value.
Solution:
We have,

It can be written as:

From the standard trigonometric table, we get






From the above values it is clear that the value of
and
are equal to
.
Therefore,
and
and equal to
. So, options B and C are correct.
The greater box is this
1.5 pound
Because pound is greater than egram.
