`(-b)xx(-b)xx(-b)=-b^3`

Express each of the products as a monomials (4/9a b c^3)xx(-(27)/5a^3b^2)xx(-8b^3c)

If 2160 = 2^(a). 3^(b) . 5^(c ) , find a, b and c. Hence calculate the value of 3^(a) xx 2^(-b) xx 5^(-c ) .

Simplify the following using the formula: (a-b)(a+b)=a^2-b^2: 113 xx\ 87 (ii) 95 xx 105

Prove that |a ,b+c, a^2,b, c+a, b^2,c, a+b, c^2|=-(a+b+c)xx(a-b)(b-c)(c- a)

Simplify and write in exponential form. a. 3^(a)xx3^(b)xx3^(c ) b. (-5)^(13)xx5^(213)

If A is 3xx4 matrix and B is a matrix such that A^T B and B A^T are both defined. Then, B is of the type (a) 3xx4 (b) 3xx3 (c) 4xx4 (d) 4xx3

Find each of the products: (-2/7a^4)xx(-3/4a^2b)xx\ (-(14)/5b^2)

Find each of the products: (7a b)xx\ (-5a b^2c)xx\ (6a b c^2)

Use the formula : (a+b) (a-b) = a^(2) - b^(2) to evaluate : (v) 7.7 xx 8.3

(x^(1/(a-b)))^(1/(a-c))xx(x^(1/(b-c)))^(1/(b-a))xx(x^(1/(c-a)))^(1/(c-b))
