If m and n are whole numbers such that mn=121, the value of (m-1)n+1 is
If m and n are whole numbers such that
mn=121,
the value of
(m-1)n+1 is
We know that
(11)2=121
So, putting values in said equation we get,
(11-1)2+1=(10)3=1000
2560.16 × (256)0.09
2560.16+0.09=2560.25=25625100
=2561/4=(44)14
=(4)4×1/4=4
What is the value of x ?
x-2=-(x-7)
x-2=-x+7
2x=9
x=9/2 = 4.5
Find the value of X. (15)3.5 × (15)x = 158
Find the value of X.
(15)3.5 × (15)x = 158
Let (15)3.5 × (15)x = 158
Then, (15)3.5+ x = (15)8
3.5 + x = 8
x = (8 – 3.5)
x = 4.5
If 5a = 625, then the value of 5(a – 2) is:
5a = 625
5a = 54
a = 4
Therefore,
5(a – 2) = 5(4 – 2) = 52 = 25
