How good are you with figures and formulas? Find out with these Mathematics past questions and answers. This Test is useful for both job aptitude test candidates and students preparing for JAMB, WAEC, NECO or Post UTME.
(\(\frac{x^a}{x^b}\))a + b = (\(\frac{x^{a + b}}{x^{a - b}}\))\(\frac{a^2}{b}\)
x-a2
xb2
xa2 - b2
\(\frac{1}{x^{a2 + b2}}\)
xb2 - a2
Correct answer is D
(\(\frac{x^a}{x^b}\))a + b = (\(\frac{x^{a2 + ab}}{x^{b2 + ab}}\))
= xa2 - b2
{\(\frac{xa + b}{xa - b}\)} = xa + b - a + b
= x2b
= x2a
= xa2 - b2
= xb2 \(\div \) a2 = \(\frac{1}{x^\text a2 + b2}\)
Find the product of (2\(\sqrt{y - 3y}\)) and (3y = 2y)
4y = y2
4y + 9y2
4y - 9y2
-4y - 9y2
2y + y2
Correct answer is C
(2\(\sqrt{y - 3y}\))(3y = 2y)
= 6y y + 4y - 9y2 - 6y\(\sqrt{y}\)
= 4y - 9y2
60o
108o
120o
150o
None of the above
Correct answer is C
The sum of interior angle of pentagon
(5 sides) = (2n - 4) x 90o
n = 5
(2 x 5 - 4) x 90o = 6 x 90o
= 540o
540o - 60o = 480o \(\div\) 4
= 120o
\(\frac{YX}{ZX}\)
\(\frac{YX}{YZ}\)
\(\frac{ZX}{YZ}\)
\(\frac{YZ}{XY}\)
Correct answer is D
The two triangles are similar
\(\frac{FG}{YZ}\) = \(\frac{FH}{XY}\) = \(\frac{GH}{YZ}\) = \(\frac{FG}{FH}\) = \(\frac{YZ}{XZ}\)
36o
60o
70o
72o
75o
Correct answer is D
\(\frac{26}{130}\) = \(\frac{x}{360}\)
130x = 26 x 360
= 9360
x = \(\frac{9360}{130}\)
= 72o
