Answer:
Hi ,
Cube of a number :
_______________
For a given number x we define cube
of x = x × x × x , denoted by x^3.
A given Natural number is a perfect
Cube if it can be expressed as the
product of triplets of equal factors.
Now ,
Write given number as product of
prime .
8788 = 2 × 4394
= 2 × 2 × 2197
= 2 × 2 × 13 × 169
= 2 × 2 × 13 × 13 × 13
= 2 × 2 × ( 13 × 13 × 13 )
Here we have only triplet of equal
factors i.e 13
To make 8788 into perfect Cube we
have multiply with 2.
Now ,
2 × 8788 = ( 2 × 2 × 2 ) × ( 13 × 13 × 13 )
17576 = ( 2 × 13 )^3 = ( 26 )^3 perfect
Cube
I hope this will useful to you.
Answer:
b. 15a +20b
Step-by-step explanation:
Given:
5 (3a+4b)
= 15a + 20b
a. 15a + 4b
Not equivalent
b. 15a +20b
Equivalent
c.5a+3a+4b
= 8a + 4b
Not equivalent
d. 5a+10a b+3b
= 15a + 4b
Not equivalent
e. 10a +5a +15b +3b
= 15a + 18b
Not equivalent
I think the answer is 12.8 mm
