Q1. Solve the equation x-5√ x -14=0

Q2. Given log₅ (4Q)+ 2 log₅ (125 P) =2, express P in terms of Q.

f4 chapter 4: indices, surds and logarithms☝🏻

since a lot are using differentiation to find min max point of a quadratic function, tho they can use -b/2a..did u guys know that if u differentiate the general form of quadratic , and set it to 0 to find the min max point, u guys get back the formula, -b/2a?

1 Addmath Question a Day
F4C10 Index Number

x - 5√x - 14 = 0
5√x = x - 14
25x = x² - 28x + 196
x² - 53x + 196 = 0
(x - 49)(x - 4) = 0
x = 49 or x = 4

When x = 49,
49 - 5√(49) - 14 = 0

When x = 4,
4 - 5√(4) - 14 = -20 ≠ 0

So x = 4 is rejected, and x = 49 is the only answer.

Do try this kbat c1+c2, for those who didn't try that day, can try today
