Here are 3 easy ways to calculate the square root of a number in Microsoft Excel - using SQRT function, POWER function and Exponential formula.

You square a number when you multiply it by itself: 5 squared is 25, since 5 x 5 = 25. Reverse the process to find square roots. The square root of 25 is 5.

A test-tube circuit made of DNA-based logic gates can calculate the square root of numbers up to 15, using DNA replication and sequence binding to conduct computations. It's excruciatingly slow ...

Researchers at Caltech have devised a way to synthesize more than 100 strands of DNA that, by passing information as they attach and detach from one another, can calculate square roots of numbers ...

It can calculate the square root of square numbers 1, 4, 9, 16, 25 and so on up to 900. The DNA computer uses a process known as hybridisation, which occurs when two strands of DNA attach together ...

DNA logic gates calculate square root using 130 different molecules A DNA-based computer uses simple base-pairing to create AND and OR logic gates … ...
