Full solution

Q. Simplify. \newline140\sqrt{140}
  1. Find Prime Factors: 140\sqrt{140}\newlineLet's find the prime factors of the radicand (the number inside the square root).\newlinePrime factorization of a number is the expression of the number as a product of its prime factors.\newline140=2×2×5×7\sqrt{140} = \sqrt{2 \times 2 \times 5 \times 7}
  2. Group and Combine Factors: 2×2×5×7\sqrt{2 \times 2 \times 5 \times 7}\newlineNow, group the identical factors.\newlineCombine the identical factors by using the exponents.\newline2×2×5×7=22×5×7\sqrt{2 \times 2 \times 5 \times 7} = \sqrt{2^2 \times 5 \times 7}
  3. Apply Product Property: 22×5×7\sqrt{2^2 \times 5 \times 7}\newlineApply the product property of radicals:\newlinea×b=a×b\sqrt{a \times b} = \sqrt{a} \times \sqrt{b}\newline22×5×7=22×5×7\sqrt{2^2 \times 5 \times 7} = \sqrt{2^2} \times \sqrt{5} \times \sqrt{7}
  4. Simplify Perfect Square: 140=22×5×7\sqrt{140} = \sqrt{2^2} \times \sqrt{5} \times \sqrt{7}\newlineSimplify the square root of the perfect square.\newlineSquare and square root cancel each other out.\newline22×5×7\sqrt{2^2} \times \sqrt{5} \times \sqrt{7}\newline=2×5×7= 2 \times \sqrt{5} \times \sqrt{7}\newline=235= 2\sqrt{35}
