Answer:
37 beads
Step-by-step explanation:
Given that:
Adel : Claire = 7 : 4
Let Adel be = A; &
Let Claire be = C
A: C = 7 : 4
7C = 4A
--- (1)
When Adel gave 68 beads to claire, we have:
C + 68 = 25:41
25(C + 68) = 41A
C + 68 =
--- (2)
Equating (1) and (2) together;
- 187 A = 175 × (-68)
-187 A = - 11900
A = - 11900/ -187
A ≅ 64
From;
C = 36.57
C ≅ 37 beads
=====================================================
Explanation:
The fourth root of x is the same as x^(1/4)
I.e,
The same applies to x^10 as well
Multiply the exponents 10 and 1/4 to get 10/4
-----------------------
If we have an expression in the form x^(m/n), with m > n, then we can simplify it into an equivalent form as shown below
The 'a' and 'b' are found through dividing m/n
m/n = a remainder b
'a' is the quotient, b is the remainder
-----------------------
The general formula can easily be confusing, so let's replace m and n with the proper numbers. In this case, m = 10 and n = 4
m/n = 10/4 = 2 remainder 2
We have a = 2 and b = 2
So
turns into
which means
