Given:
The equation is
To find:
The inverse operation for the equation using the knowledge of inverse operations.
Solution:
We have,
Here, 4560 is divided by 120. So, in this equation the operation is division.
We know that inverse operation of division is multiplication. So, multiply both sides by 120.
It can be written as
The inverse operation for the equation is .
Therefore, the correct option is B.
(See attached diagram.) The positions of the vaulter's left and right hands are marked. The length of the entire pole is 15 feet. The segment below her left hand is twice as long as the segment above, so label those two parts with x and 2x. Those two segments add up to 15 feet:
The lower segment is 10 feet long. The vaulter's right hand is 1.5 feet above her left, so it is 10 + 1.5 = 11.5 from the bottom of the pole.
(d) 18/48
That’s the only value that’s not negative compared to the rest
1.
write 1 as
so that we compare same base logarithms:
2. Neglect the equal bases and write the arguments:
So
repeat step 1, that is write 4 as a logarithm with base 4:
